This invention relates to a package discharge for tying machines, andthe object of the invention is to take the packages away from themachine as soon as the tie around the package has been completed.

This package discharge consists of a pair of belts and a plurality ofnotchedf disks which disks and one end of the pair of belts rises tolift the package ofi' of the support upon which it is placed during the,time the tie is being made around it, and carry-it away from the tyingmachine to discharge it upon a table or other endless belt for takingthe package to a place of storage. f

It will be understood by those skilled in the art that the machine uponwhich this discharge is applied carries packages so rapidly that it isvery diiiicult for the attendant to push the packages through themachine with sufficient rapidity to get the tied package out of the wayof the package to be tied, unless the workman can devote his entireattention to the placing of the new package to be tied, and then he hasall he can do to keep the package placed'in the proper position fortying without attending to the discharge of the package that has beentied.

Other objects of the invention will be apparent as the descriptionproceeds.

An embodiment of the invention is shown in the accompanying drawings inwhich the same reference numeral is applied to the same portionthroughout the several figures of the drawings, and of which there maybe modifications.

Figure 1 is' a vertical elevation of the discharge side of a tyingmachine of this type showing the discharge belt applied thereto,

Figure 2 isa view partly in section at the discharge belt,

Figure 3 is a sectional view of the pulleys used to carry the dischargebelt,

Figure 4 is a plan view of the discharge table at the discharge belt,and f Figure 5 is a view partly in section of a detail showin thedriving gears for driving the discharge belt.

vThe tying machine is of a well known type in which there is a base 1containing most 192s. i serial v No. asaalsm..

upwardly from this base is a heavy fixed ring 2 which carries aIplurality of wheels 3, 4, 5 and 6 lfor'the support of the rotary shuttlerinJg 7.

ust in frontv of the machine there is a table 8 which has a fixed sidefence 9 to align the packages against it when they are to betied; aJogger 10 causing the packages to be pushed against the fence andholding them in that position until -the tie, has been completed. Themachine is driven from the motor M wh1ch sits upon the bracket 12 at oneside of the main ring 2. The motor has two pulleys 13 and 14 aroundwhich pulleys pass the belts 15 and 16 respectively. The belt 16 drivesthe mam pulley 17 which is on a shaft 18 carrying a worm gear whichdrives the worm wheel 19, the latter on the shaft 20.

.The shaft 20 has the key 21 in engagement with the cam gear 22, saidcam gear having a groove on one side thereof to receive the roller 23which is secured to an arm 24 for the operation of the link 25 whichraises and lowers the package discharge belt. The shaft 20 also carriesa pulley 26 which is pivotally connected by means of the pin 27 to apitman 28, said pitman having a series of teeth thereon which engage theteeth of the spur gear 30.

The spur gear 30 is secured to a shaft 31 which is journalled in boxes32, 33 and has a bevel gear 34 thereon to drive the bevel gear 35 whichoperates that portion of the tying machine which is engaged in makingthe tie and rotating the ring 7 but which forms no part ofthe presentinvention.

Extending from the rearward side'of the ring 2 are three table members36, 37, 38.

The shaft 41 is journalled in two bearings 47, 48 which are bolted ontothe side ofthe frame of the machine at the back of the ring 2 by meansof two brackets49, 50. The bearing 47 has an arm 51 mountedthereon whichcarries a stud shaft 52 for the support of the belt tightener 53. Thehubof the arm 51 is split and has two lugs 54, 55 which enable the bolt56 to tighten the hub on the extension of the bearingv47' to, hold l thebelt tightening pulley 53 in a given adjustment. The belt 57 passesaround the pulley 53 around the pulley 42 and then around a pulley 59just back of the table, the latter pulley being loosely mounted on ashaft 60. Upon the shaft is also loosely mounted a rear pulley for thebelt 61. c

The belt 61 passes around the llilghtemng pulley 62,'and around thefront p Well as over the pulley 64. The belt 57 also passing over asimilar pulley 64 to allow the link 25 to raise and lower the beltwithout, increasing their tension materially by reason of the fact thatboth of them pass over the two pulleys 64, 64 on the shaft 41.

The belt tightener pulley 62 is carried by a stud shaft 65, the same asthe stud shaft 52 and the arm 66 supports it. Both the arms 51 and 66are supported on extensions of the bearings 47, 48 and are locked intheir positions by bolts 56 passing through the arm lugs 54 and 55, oneset for each arm. v

In order to provide for driving the belts 57 and 61 there is a housing70 at the end of the bearing 48 to cover the drive gears and formbearings therefor. This housing 70 has beare ings for the shaft 41, 76and 78 which are also j ournalled in the cover plate 71.

The shaft 41 is driven by the gear 74, gear 75, gear-77 on the shaft 78,bevel gear 79 on the shaft 78 and bevel gear 80 on the shaft g, thelatter shaft carrying the drive pulley In operation the cam 26 whichdrives the lever 24 and raises and lowers the belt with its associatedserrated disk pulleys operates to raise the belt and serrated disks atthe end of the cycle of the tying mechanism. In other words as soon asthe tie is completed and any other thing that has to be done withrespect to the tie is effected the cam comes intomovement to engage theserrated disks with the bottom of the box, and thereby carry the bundleaway from the machine, the belt aiding the serrated disks. The disksoperate all the time but do not move the box until the tie is complete.

It will also be seen that the entire Weight of the box or bundle iscarried by the table during the period of tying, that there is no dangerof the box moving at the wrong time, but the belts are always liftedhigher than the table so they carry all of the weight of the box andquickly move it away from the machine.

Having thus described my invention, what I desire to secure by LettersPatent of the United States is as follows, but modifications may be madein carrying out the invention as shown in the drawings and in the aboveparticularly described form thereof, Within the purview o f the annexedclaims.
